Abstract
The paper presents experimental data on improvement of cyclic fatigue life of stainless steel and aluminium alloy samples as a result of treatment based on direct passage of electric current through the material, as well as data of calculationexperimental studies of residual welding stress relaxation under the impact of induced electric current. Results of investigation of the influence of current treatment on residual stresses in the coating and in the material after grinding are given.
